Question 635022
The coordinates of intersection are (1,0) & (0,5)

x1		y1	x2	y2									
1		0	0	5									
													
slope m =		(y2-y1)/(x2-x1)											
(	5	-	0	)/(	0	-	1	)					
(	5	/	-1	)  									
m=		-5    						 					
The required line passes through both the points. So we select one point and plug it with the slope 													
Plug value of  the slope  and point			(	1	,	0	) in						
Y	=	m	x	+	b								
0.00	=	-5    	*	1	+	b							
0.00	=	-5    	+	b									
b=	0    	+	5    										
b=	-5      												
So the equation  will be													
Y 	=	-5    	x	+	5
